riak-0.5
By popular demand, this release changes the identifier type for
buckets (Riak's namespaces) from atoms to binaries. Old code using
the native interface must change accordingly; code using the jiak http
interface will continue to work unchanged. To convert an old
cluster's storage, simply do a backup and restore -- this will convert
all of the data on the way back in.
riak_client:
- preferred use is now riak:client_connect(Nodename) instead of IP/Port
- bugfix where timeouts could cause incorrect responses
eventers:
- no longer gen_event, now using simple erlang messaging
- fully capable matchspecs now available for event matching
- use monitor to watch for death of handlers
- the example riak_event_logger is now a little friendlier
riak_backup:
- more robust due to explicit ring fetch and node connection
testing:
- more coverage, especially of backend interface, riak_object
mapreduce:
- less messaging via batched groups to each vnode
- intermediate per-vnode reduce phase
build process:
- much more useful error message when building with erlang < R13
ring management:
- simplify metadata structure
- fix filtered_preflist bug in case of small number of nodes
- internal naming cleanup
- prune old state files more aggressively
configuration:
- new 'start_apps' param for starting dependency applications
(useful for some custom storage backends)
native client interface:
- added list_buckets and filter_keys
client libraries:
- url-style quoting of buckets and keys in http client content
- initial version of ruby client
- java client uses List instead of ArrayList
